The calorific value of the fuel is the amount of energy released per kg
You have the value of the total energy released so find from those two numbers the mass of fuel (in kg) that was used.
Convert that mass to volume using the density.
Convert volume to litres.
You then have the volume of fuel used in litres and you know the cost.
You have the cost per litre.
